engineer will not hear the musicians "live" through the deck unless it is actually in
record mode.
To select Mode 2, press and hold SET LOCATE and press AUTO INPUT
MONITOR. The counter will briefly display 'tAPE', indicating Mode 2. To switch
back to Mode 1, press and hold SET LOCATE and press AUTO INPUT
MONITOR. The counter will briefly display 'In', indicating Mode 1.
The reason for having these two options is to accommodate different stages of the
recording process. Auto Input Off is the "normal" option and is what you would use
when first recording tracks. As you record, you want to monitor the input signal being
recorded, as well as any signals from tracks you've already recorded on tape.
However, when doing punch-ins and overdubs, Auto Input will probably be On so that
you can hear what was recorded on tape for a given track right up to the point you
want to punch in. As soon as ADAT punches into Record mode, the taped signal
drops out as the monitor switches over to the input signal so you can hear what's
being recorded to tape. After punch out, the track reverts to monitoring what's on
tape.

3.2C All Input Monitor

With this function on (ALL INPUT MONITOR LED lit), the auto input monitor setting is
overridden so that all tracks monitor their input signals regardless of their record
enable status. All eight track INPUT LEDs will be lit.
With All Input Monitor off, the Auto Input Monitor setting determines track monitoring.

3.2D Digital Input

This switch determines whether ADAT will record from its analog inputs (balanced or
unbalanced) or digital input. To record from the digital input, press the switch; its LED
will light. All eight channels will be received via the fiber optic connection (section 6.1)
and the analog inputs will be ignored.
DIGITAL IN can be turned on or off only when the ADAT is in STOP mode. When
recording while DIGITAL IN is on, the ADAT's speed is slaved to the clock of the
incoming digital signal. The PITCH controls will have no effect when recording from the
digital inputs, although they will remain lit. Do not turn on DIGITAL IN if nothing is
connected to the digital input, since the ADAT will "hunt" for a clock that isn't there,
causing long sync times. (For the one exception to this rule, see Section 6.1A.)

SETTING LEVELS

Unlike analog tape recorders, whose meters indicate "0 VU" at the ideal nominal
recording level, with 10 to 15dB headroom above the point, 0dB on ADAT represents
